Discussion on the “repulsion induction motor,” at Milwaukee, Wis., May 28, 1906

C. P. Steinmetz: I desire to draw your attention to some features of this paper. It is a report of the work done by my assistant, Mr. Milch, in developing a type of alternating-current motor intermediary between the polyphase induction motor and the single-phase series motor; that is, a motor having constant- and limited-speed characteristics combined with very high starting torque, and high torque efficiency and power-factor at starting and at low and intermediate speeds. The repulsion motor and the compensated series motor give a very high torque at starting and at low speeds, but an unlimited speed; that is, the speed increases indefinitely with decreasing load.
